Hearing loss
- Hearing loss can be present at birth (congenital) or become evident later
in life (acquired deafness). The distinction between acquired and congenital
deafness specifies only the time that the deafness appears. It does not specify
whether the cause of the deafness is genetic (inherited).
- Acquired deafness may or may not be genetic. For example, it may
be a manifestation of a delayed-onset form of genetic deafness. Alternatively,
acquired deafness may be due to damage to the ear from noise.
- Congenital deafness similarly may or may not be genetic. For example,
it may be associated with a white forelock and be caused by a genetic disease
called Waardenburg syndrome. In fact, more than half of congenital hearing
loss is inherited. Alternatively, congenital deafness may be due to something
such as the rubella virus to which the mother was exposed during pregnancy.
